  • Microsoft launches Copilot in Power Pages, an AI-powered assistant for its low-code business website creation tool.

  • Copilot can generate text, forms, chatbots, web page layouts, and design themes based on user prompts.

  • Users can describe the form they need, and Copilot will build it and generate necessary database tables.

  • Copilot in Power Pages allows users to go from no code to low code to pro code seamlessly.

  • The AI assistant is powered by OpenAI's GPT-3.5 model and has safeguards in place to prevent irrelevant or inappropriate suggestions.

  • Copilot is designed to assist human website makers, giving them control over applying or tweaking its suggestions.

  • Snowflake acquires Neeva, a search startup founded by former Google executives, for an undisclosed amount.

  • The acquisition is expected to enhance Snowflake's ability to offer intelligent and conversational search experiences to its customers.

  • Neeva, initially focused on creating a subscription-based search engine without ads, announced the shutdown of its consumer search product and a pivot towards enterprise use cases.

  • Snowflake aims to bring a new type of experience to its users by integrating Neeva's technology, which enables conversational experiences.

  • The acquisition aligns with Snowflake's strategy to leverage large language models (LLMs) and generative AI for data-driven insights.

  • Snowflake reported strong revenue growth but gave lower-than-expected product revenue guidance for the second quarter, leading to a decrease in share value.

  • Meta introduces LIMA, a new language model that achieves GPT-4 and Bard level performance with relatively few examples.

  • LIMA is fine-tuned using 1,000 manually selected diverse prompts from various sources.

  • Human evaluators preferred LIMA's answers over GPT-4, Google Bard, and text-davinci-003 in a significant percentage of cases.

  • Meta's research suggests that pre-training plays a crucial role in a language model's knowledge acquisition, and limited fine-tuning is sufficient for generating high-quality content.

  • The findings challenge the notion that extensive human feedback training is essential for model performance.

  • Meta refers to this as the "superficial alignment hypothesis," emphasizing the importance of teaching models a particular style during fine-tuning.

  • LIMA has limitations in dataset creation and robustness compared to existing models like GPT-4.

  • Despite its limitations, LIMA demonstrates that aligning and fine-tuning AI models can be achieved with a simple approach.

  • Meta's head of AI research, Yann LeCun, believes large language models will undergo significant changes in the medium term.

The SunZia SouthWest Transmission Project, which aims to harvest 3,500 megawatts of wind energy in New Mexico and transport it to other parts of the western US, has achieved a key milestone with approval from the US Department of the Interior. This step brings the $2 billion project closer to reality after 16 years of development. The project involves building two twin 500-kilovolt lines across 520 miles of federal, state, and private lands, from central New Mexico to central Arizona. The Bureau of Land Management anticipates that SunZia will deliver 4,500 megawatts from New Mexico to Arizona and California, with the majority originating from the SunZia Wind Project in New Mexico. The initiative is aligned with President Biden's goal of a 100% clean electricity grid by 2035. Construction is expected to begin in the coming weeks and the project is set to be completed by 2026.

Engineers at the University of Massachusetts Amherst have developed a method to continuously generate electricity from the humidity in the air. This innovative approach, called the "generic Air-gen effect," utilizes any material with nanopores smaller than 100 nanometers to create a charge imbalance, functioning as a battery as long as there is humidity present. This discovery could enable cost-effective, continuous electricity generation from a variety of materials, providing a solution for the limitations of condition-dependent renewables like solar and wind power.

France has passed a law banning domestic flights that can be replaced by train journeys under two and a half hours, encouraging the use of trains as a lower-carbon alternative. Air France has already cancelled three routes due to high carbon emissions. However, critics argue that the law will have a minor effect on carbon emissions, with loopholes allowing some short-haul flights to continue. Although the law is seen as a positive step towards reducing greenhouse gas emissions, its true impact on combating climate change remains uncertain.


Mercedes-Benz has announced plans to introduce an electric version of its CLA sedan to the US market next year, positioning it as a rival to the Tesla Model 3. This development was unveiled at Mercedes' annual North American dealer meeting. The electric CLA is expected to have a driving range of about 400 miles and feature a digital-first cockpit design. The German automaker also aims to launch an electric version of the GLC crossover to succeed its EQC electric crossover, the first mass-market EV for the US from the brand. Mercedes-Benz is planning to roll out EVs more quickly in states with higher adoption rates and aims to go fully electric by 2030 where market conditions permit.

BMW has unveiled the electric i5, a first for its 5 Series lineup, with new features such as in-car gaming and eye-activated lane changes. The electric BMW i5, expected to deliver 590 horsepower in its M performance version, promises a unique driving experience, incorporating the latest in technological innovation. It includes a hands-free driving option up to 85 mph, under certain conditions, and a lane change feature that requires just a glance at the side mirror to initiate. The car also supports in-car gaming when stationary, with the ability to connect smartphones as controllers.

As Aurora prepares to launch its autonomous service, Aurora Horizon, the company has shared a video demonstrating how its autonomous driving technology, Aurora Driver, operates in low visibility conditions. The software autonomously responds to rain, snow, and fog, slowing the vehicle and proceeding with caution. Aurora's technology even includes a sensor cleaning solution for improved navigation in challenging conditions. If conditions become too dangerous, the Aurora Driver will reduce speed and find a safe spot to halt, notifying Aurora's Command Center.
